This Blood pressure Monitor Wrist Pulse Meter works like a charm. I had just gone to the doctors today and when they took my blood pressure I had them to right it down for me so when I got home I could test this one and see if it was same It was pretty close only a few numbers off. This one has a auto turn off and a low battery indicator. It is easy to use and out on. It has a – set + on one side and the there is a M and on button on another side. I display is nice and large and easy to read. You will need battery they are not included. It holds closed buy velcro. I also like that is comes with a case to put it back into when not in use. It is good quality and made well.
